70R2076S Red Dot 6 × 6 Straight Splicer Steel Fitting with R134a Quick-Disconnect Service Port (16 mm)

The Red Dot 70R2076S Straight Splicer with R134a Quick-Disconnect Service Port is designed to join two same-size 6 × 6 refrigerant hoses in mobile HVAC systems. Because it uses a straight splicer configuration, it allows clean, inline hose repairs without altering routing or layout.

This fitting features an integrated 16 mm R134a quick-disconnect service port, which enables technicians to evacuate, charge, and service the system using standard R134a couplers. As a result, it speeds up service work and reduces the need for additional adapters or fittings.

In addition, the steel construction improves strength and durability in high-pressure refrigerant applications. Therefore, it performs well in trucks, buses, and off-highway equipment operating in demanding environments.

Because this part is widely cross-referenced across OEM and aftermarket catalogs, it remains a trusted choice for mobile refrigeration service and repair.
